You need to take the car to Autozone or any parts store and have the OBD-I system codes read. If your radiator coolant is low, its not rocket science...top it off. Just so you know, the cooling system on these cars is a known weak point.

Yeah I kinda felt stupid when I aske that and I know now that I don't have any cooling problems cause I ran my car at about 90 for like 250 miles the other day and not a hiccup! Plus even when I run the piss out of it (floor it from stop light to stop light). It gets more responsive and the needle of my temp gauge never goes pat the middle and I can always touch my valve covers when I turn it off and radiator hose an wont get burnt! I do have an oil leak at the moment though! And I think my speed sensor might be goin out also because my miles won't register sometimes and the speedo will go out.

The speed sensor for the speedometer is in the dif housing - looks a bit like a CPS. I think other speed related devices and systems get information from this unit too. Start checking there but check out wires etc carefully first - no point in buying a unit for a damaged wire.
